1. An access node comprising:
a first wireline interface that receives a first wireline signal from a first wireline link coupled to a cellular base station;
a demodulator coupled to the first wireline interface, the demodulator generates an analytic signal from the first wireline signal by sampling the first wireline signal at a first sampling rate;
an interpolator coupled to receive the analytic signal, the interpolator generates an interpolated signal by interpolating the analytic signal at a second sampling rate, the second sampling rate being different from the first sampling rate;
a frequency-scaling buffer coupled to receive the interpolated signal, the frequency-scaling buffer stores a plurality of sampled symbols within the interpolated signal and subsequently prepares the stored plurality of sampled symbols for use in wireline communication;
a digital-to-analog converter that converts the digital signal into an analog signal; and
a second wireline interface that transmits the analog signal on a second wireline link.
